Steve Jobs' rant against Android, RIM, and 7" tablets couldn't go by unnoticed, of course. We already had the rather dry response from Google's Andy Rubin, but Mountain View isn't the only one who responded. TweetDeck's CEO wasn't particularly pleased by Jobs distorting TweetDeck's story on developing for Android, and now we have RIM's co-CEO Jim Balsillie who slammed Cupertino pretty hard.

Great point. Even if it's not hard to write an app that runs stably across the hundred software/hardware combinations, you still can't be sure the app doesn't crash unless you've tested it on on every single one of them. That's the daunting part.

You're right. As someone who has developed desktop software, I always made sure to buy every possible combination of computer hardware and test my software on those boxes so that I can be sure that I knew it worked.
